[MPlayer-dev-eng] [PATCH] af_pan.c: Avoid zero output channels when reinit af pan

[Zuxy Meng]

Hi,

af pan doesn't allow zero output channel at initialization, which
makes it impossible to af_add it. This patch initialize the number of
output channels as the same as that of input channels.

It might fix Bug 818 too but I'm unsure about that.
